$A$ Zener diode is used for

The figure shows a $DC$ voltage regulator circuit with a Zener diode of breakdown voltage $= 6\,V$. If the unregulated input voltage varies between $10\,V$ to $16\,V$, then what is the maximum Zener current in $mA$ (in $.5$)?

The reverse breakdown voltage of a Zener diode is $5.6\, V$ in the given circuit. The current $I_z$ through the Zener is......$mA$

Choose the correct statement about $Zener$ diode.

The $I-V$ characteristics of an electronic device are shown in the figure. The device is $:-$

$A$ Zener diode of breakdown voltage $10 \, V$ is used as a voltage regulator as shown in the figure. The current through the Zener diode is (in $ \, mA$)
